DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. It is to be understood by those of ordinary skill in this technological field that other embodiments may be utilized, and structural, electrical, as well as procedural changes may be made without departing from the scope of the present invention. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

As used herein, the terms ‘module’, ‘unit’ and ‘part’ are used for elements in order to facilitate the disclosure only. Therefore, significant meanings or roles are not given to the suffixes themselves and it is understood that the ‘module’, ‘unit’ and ‘part’ can be used together or interchangeably.

FIG. 1 is a block diagram of terminal 100 in accordance with an embodiment of the present invention. The terminal 100 may be implemented as a variety of terminal types. Examples of such terminals include mobile phones, user equipment, smart phones, computers, digital broadcast terminals, personal digital assistants, portable multimedia players (PMP), and navigators.

By way of non-limiting example only and for convenience and conciseness of the following description, the present invention is illustrated as a mobile phone. It is not intended to limit the scope of the present invention. The teachings of the present invention apply equally to other types of terminals.

FIG. 1 shows the terminal 100 having various components, but it is understood that implementing all of the illustrated components is not a requirement. Greater or fewer components may alternatively be implemented.

FIG. 1 shows the terminal 100 having a wireless communication unit 110 configured with various components. The broadcast receiving module 111 receives a broadcast signal and broadcast associated information from an external broadcast managing entity via a broadcast channel.

The broadcast channel may include a satellite channel or a terrestrial channel. The broadcast managing entity may be a system which transmits a broadcast signal or broadcast associated information.

Examples of broadcast associated information include information associated with a broadcast channel, a broadcast program, or a broadcast service provider. For example, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) or electronic service guide (ESG) of digital video broadcast-handheld (DVB-H).

The broadcast receiving module 111 may receive broadcast signals transmitted from various types of broadcast systems. By nonlimiting example, such broadcasting systems include digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), the data broadcasting system known as media forward link only (MediaFLO®), and integrated services digital broadcast-terrestrial (ISDB-T).

The broadcast receiving module 111 may also receive multicast signals. Data received by the broadcast receiving module 111 may be stored in a suitable device, such as the memory 160.

The mobile communication module 112 transmits and receives wireless signals to and from one or more network entities, such as a base station or a Node-B. The wireless signals may represent audio, video, multimedia, control signaling, or data.

The wireless Internet module 113 provides Internet access for the terminal 100. The wireless Internet module 113 may be internally or externally coupled to the terminal 100.

The short-range communication module 114 facilitates short-range communications. Suitable technologies for implementing the short-range communications module 114 include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee™.

The position-location module 115 identifies and obtains the location of the terminal 100. The position-location module 115 may be implemented using global positioning system (GPS) components which cooperate with associated satellites and network components.

The audio/video (A/V) input unit 120 provides audio or video signal inputs to the terminal 100. The A/V input unit 120 may include a camera 121 and a microphone 122. The camera receives and processes image frames of still pictures or video.

The microphone 122 receives an external audio signal while the terminal 100 is in a particular mode, such as a phone call mode, a recording mode, or a voice recognition mode. The audio signal is processed and converted into digital data. The terminal 100 and A/V input unit 120 may include assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.

Data generated by the A/V input unit 120 may be stored in the memory 160, utilized by the output unit 150, or transmitted via one or more modules of communication unit 110. The terminal 100 may include two or more microphones 122 or cameras 121.

The user input unit 130 generates input data in response to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad, a jog wheel, and a jog switch.

The sensing unit 140 provides status measurements for various aspects of the terminal 100. For example, the sensing unit may detect an open and close state of the terminal 100, relative positioning of components of the terminal, a change of position of the terminal, a change of position of a component of the terminal, a presence or absence of user contact with the terminal, orientation of the terminal, or acceleration or deceleration of the terminal. The sensing unit 140 may also sense the presence or absence of power provided by the power supply 190 and the presence or absence of a connection between the interface unit 170 and an external device.

The interface unit 170 may be implemented to connect the terminal with an external device. External devices include wired and wireless headphones, external chargers, power supplies, storage devices configured to store data, or microphones. The interface unit 170 may be configured using a wired and wireless data port, a memory card socket, audio input and output ports (I/O), or video I/O ports.

The interface unit 170 may act as a passage for supplying the mobile terminal 100 with a power from the cradle or delivering various command signals input from the cradle if the mobile terminal 110 is connected to an external cradle. Each of the various command signals input from the cradle or the power may operate as a signal enabling the mobile terminal 100 to recognize that it is correctly loaded in the cradle.

The output unit 150 outputs information associated with the terminal 100. The display 151 is typically implemented to display information associated with the terminal 100. For example, the display 151 may provide a graphical user interface which includes information associated with a phone call if the terminal is operating in a phone call mode. The display 151 may display images which are associated with various modes, such as a video call mode or a photographing mode.

The display 151 may be configured as a touch screen working in cooperation with the input unit 130, in one embodiment of the present invention. This configuration allows the display 151 to function both as an output device and an input device.

The display 151 may be implemented using known display technologies such as a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display, or a three-dimensional display. The terminal 100 may include one or more displays 151. An example of a two-display embodiment is one in which one display 151 is configured as an internal display which is viewable when the terminal 100 is in an opened position and a second display configured as an external display which is viewable in both the open and closed positions.

The touchscreen can be configured to detect a touch input pressure as well as a touch input position and size.

Meanwhile, a proximity sensor (not shown) may be provided within or around the touchscreen. The proximity sensor detects an object approaching a prescribed detecting surface or a presence or non-presence of an object existing around itself using an electromagnetic power or infrared rays without mechanical contact.

Example of the operational principle of the proximity sensor are explained as follows. First, an oscillation amplitude of the oscillation circuit attenuates or stops if an object approaches a sensor detecting surface while an oscillation circuit oscillates a sine radio frequency. This change is converted to an electric signal to detect a presence or non-presence of the object. Therefore, a proximity switch may detect any non-metallic object without interference.

Additionally, an electrostatic may be configured to detect the proximity of a pointer via an electric field change attributed to the proximity of the pointer.

The sensor may detect a position of the pointer and a distance between the pointer and the touchscreen if the pointer is placed in the vicinity of the touchscreen without being actually contacted with the touchscreen. For clarity and convenience of explanation, an action for enabling the pointer approaching the touchscreen to be recognized as placed on the touchscreen is referred to as a ‘proximity touch’ and an action of enabling the pointer to actually come into contact with the touchscreen is referred to as a ‘contact touch’. Additionally, a position at which the proximity touch is made to the touchscreen using the pointer is referred to as the position of the pointer vertically corresponding to the touchscreen when the pointer makes the proximity touch.

FIG. 1 further shows the output unit 150 having an audio output module 152. The audio output module 152 may be implemented using one or more speakers, buzzers, or other audio producing devices.

The audio output module 152 functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, or a broadcast reception mode. The audio output module 152 outputs audio relating to a particular function, such as a call notification, a message notification, or a error notification.

The output unit 150 is further shown having a vibration module 153, which may be used to identify the occurrence of an event associated with the terminal 100. An example an output of vibration module 153 includes a vibration as a notification to a user.

The vibration module 153 may vibrate when the terminal 100 receives a call or message. Vibration may also be provided by the vibration module 153 in response to receiving user input at the terminal 100, thereby providing a tactile feedback mechanism. It is understood that the various outputs provided by the components of output unit 150 may be performed separately or performed using any combination of the components.

The memory 160 may store various types of data to support the processing, control, or storage requirements of the terminal 100. Examples of such data include program instructions for applications operating on the terminal, contact data, phonebook data, messages, pictures, or video.

The memory 160 shown in FIG. 1 may be implemented using any type of volatile and non-volatile memory or storage devices. Such devices may include random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, card-type memory, or other similar memory or data storage device.

The controller 180 controls the overall operations of the terminal 100. For example, the controller 180 performs the control and processing associated with voice calls, data communications, video calls, camera operations, and recording operations.

The controller 180 may include a multimedia module 181 which provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180 or may be implemented as a separate component.

Moreover, the controller 180 is able to perform a pattern recognizing process for recognizing a writing input and a picture drawing input carried out on the touchscreen as characters or images.

The power supply 190 provides power to the various components of the terminal 100. The power provided may be internal power or external power.

Various embodiments described herein may be implemented in a computer-readable medium using computer software. The various embodiments may also be implemented in hardware.

A hardware implementation may be implemented using one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, or other electronic units designed to perform the functions described herein. Some embodiments are implemented by controller 180.

A software implementation of the embodiments described herein may be implemented with separate software modules, such as procedures and functions, each of which perform one or more of the functions and operations described herein. The software code may be implemented with a software application written in any suitable programming language and may be stored in the memory 160 for execution by the controller 180 or a processor.

The terminal 100 may be implemented in a variety of different configurations. Examples of such configurations include folder-type, slide-type, bar-type, rotational-type, and swing-type.

For clarity, further disclosure will primarily relate to a slide-type terminal 100. However such teachings apply equally to other types of terminals 100. FIG. 2 is a perspective view of a front side of a terminal 100 according to an embodiment of the present invention. As shown in FIG. 2, the terminal 100 is shown having a first body 200 configured to slideably cooperate with a second body 205.

The first body 200 slides relative to second body 205 between open and closed positions. The first body 200 is positioned over the second body 250 in the closed position such that the keypad 215 is substantially or completely obscured by the first body 200. The user may access the keypad 215, the display 151, and function keys 210 in the open position. The function keys 210 may be configured for a user to enter commands such as start, stop, or scroll.

The user input unit 130 is implemented using the function keys 210 and keypad 215. The function keys 210 are associated with the first body 200 and the keypad 215 is associated with the second body 205. The keypad 215 includes various keys such as numbers, characters, and symbols, to enable a user to place a call, prepare a text or multimedia message, and operate the terminal.

The terminal 100 is operable in either a standby mode or an active call mode. Typically, the terminal 100 functions in the standby mode when in the closed position and in the active mode when in the open position. The mode configuration may be changed as required or desired by the user.

The first body 200 is shown formed from a first case 220 and a second case 225 and the second body 205 is shown formed from a first case 230 and a second case 235. The respective first 220, 230 and second 225, 235 cases may be formed from a suitably ridge material such, as injection molded plastic, or formed using metallic material, such as stainless steel (STS) and titanium (Ti).

One or more intermediate cases may be provided between the first case 220 and second case 225 of the first body 200 or between the first case 230 and second case 235 of the second body 205. The first body 200 and the second body 205 may be sized to house electronic components necessary to support operation of the terminal 100.

The first body 200 is shown having a camera 121 and audio output module 152. The camera 121 may be selectively positioned such that it may rotate or swivel relative to the first body 200.

The function keys 210 are positioned adjacent to a lower side of the display 151. The display 151 is shown implemented as an LCD. The display 151 may also be configured as a touchscreen having an underlying touchpad which generates signals responsive to user contact with the touchscreen.

The second body 205 is shown having a microphone 122 positioned adjacent to the keypad 215 and side keys 245 positioned along the side. The side keys 245 may be configured as hot keys, such that the side keys are associated with a particular function of the terminal 100.

An interface unit 170 is shown positioned adjacent to the side keys 245. A power supply 190 in a form of a battery is located on a lower portion of the second body 205.

FIG. 3 is a rear view of the terminal 100 shown in FIG. 2. As shown in FIG. 3, the second body 205 includes a camera 123, a flash 250, and a mirror 255.

The flash 250 operates in conjunction with the camera 123. The mirror 255 is useful for assisting a user to position the camera 123 in a self-portrait mode.

The camera 123 of the second body 205 faces a direction opposite to a direction faced by the camera 121 of the first body 200. The camera 121 of the first body 200 and camera 123 of the second body 205 may have the same or different capabilities.

In one embodiment, the camera 121 of the first body 200 operates with a relatively lower resolution than the camera 123 of the second body 205. Such an arrangement works well during a video conference in which reverse link bandwidth capabilities may be limited. The relatively higher resolution of the camera 123 of the second body 205 is useful for obtaining higher quality pictures.

The second body 205 also includes an audio output module 153 configured as a speaker which is located on an upper side of the second body. The audio output module 152 of the first body 200 and the audio output module 153 of second body 205 may cooperate to provide stereo output. Moreover, either or both of the audio output modules 152 and 153 may be configured to operate as a speakerphone.

A broadcast signal receiving antenna 260 is shown located at an upper end of the second body 205. The antenna 260 functions in cooperation with the broadcast receiving module 111. The antenna 260 may be fixed or configured to retract into the second body 205.

The rear side of the first body 200 includes a slide module 265. The slide module 265 which slideably couples with a corresponding slide module (not shown) located on the front side of the second body 205.

It is understood that the illustrated arrangement of the various components of the first body 200 and the second body 205 may be modified as desired. Some or all of the components of one body may alternatively be implemented on the other body. In addition, the location and relative positioning of the components are not critical to many embodiments and, therefore, the components may be positioned at locations which differ from those shown by the representative figures.

The terminal 100 may operate in a communication system capable of transmitting data via frames or packets. The communication system may include wired communication, wireless communication, or satellite-based communication system.

The communication system may utilize various systems such as frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), universal mobile telecommunications system (UMTS), long term evolution (LTE) of the UMTS, or the global system for mobile communications (GSM). By way of non-limiting example, further description will relate to a CDMA communication system, but such teachings apply equally to other system types.

As shown in FIG. 4, a CDMA wireless communication system is shown having a plurality of terminals 100, a plurality of base stations (BS) 270, base station controllers (BSC) 275, and a mobile switching center (MSC) 280. The MSC 280 is configured to interface with a conventional public switch telephone network (PSTN) 290 and is also configured to interface with the BSCs 275.

The BSCs 275 are coupled to the BSs 270 via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. It is to be understood that the system may include more than two BSCs 275.

Each BS 270 may include one or more sectors, each sector having an omnidirectional antenna or an antenna pointed in a particular direction radially away from the BS 270. Each sector may include two antennas for diversity reception. Each BS 270 may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum.

The intersection of a sector and frequency assignment may be referred to as a CDMA channel. The BSs 270 may also be referred to as base station transceiver subsystems (BTSs). In an alternate embodiment, the term “base station” may be used to refer collectively to a BSC 275 and one or more BSs 270.

The BSs 270 may also be denoted “cell sites.” Alternatively, individual sectors of a given BS 270 may be referred to as cell sites.

A broadcasting transmitter (BT) 295 is shown broadcasting to terminals 100 operating within the system. The broadcast receiving module 111 of the terminal 100 is configured to receive broadcast signals transmitted by the BT 295. Similar arrangements may be implemented for other types of broadcast and multicast signaling.

FIG. 4 also shows several global positioning system (GPS) satellites 300. The GPS satellites 300 facilitate locating the position of some or all of the terminals 100. The position-location module 115 of the terminal 100 is typically configured to cooperate with the satellites 300 to obtain position information.

Other types of position detection technology may be used in addition to or instead of GPS location technology. Some or all of the GPS satellites 300 may alternatively or additionally be configured to provide satellite DMB transmissions.

The BSs 270 receive sets of reverse-link signals from various terminals 100 during operation of the wireless communication system. The terminals 100 are performing calls, messaging, or other communications.

Each reverse-link signal received by a BS 270 is processed within that BS. The resulting data is forwarded to an associated BSC 275.

The BSC 275 provides call resource allocation and mobility management functionality including soft handoffs between base stations 270. The BSCs 275 also route the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN interfaces with the MSC 280 and the MSC interfaces with the BSC 275, which in turn control the BSs 270 to transmit sets of forward-link signals to the terminals 100.

In the following description, steps of a broadcast controlling method of a terminal 100 according to the present invention are explained one-by-one with reference to FIG. 5 as follows. FIG. 5 is a flowchart for a broadcast information reception method of a terminal according to a first embodiment of the present invention. Hereinafter, a display screen of the touchscreen 151 shall be indicated by a reference number 400.

A method of controlling a mobile terminal according to a first embodiment of the present invention is explained with reference to FIGS. 5 to 7 as follows.

FIG. 5 illustrates a flowchart for a method of controlling a mobile terminal according to a first embodiment of the present invention.

As illustrated in FIG. 5, a list of messages is displayed on a display (S51). A user may touch and drag the list of messages (S52). If the list is dragged in a first direction, a preceding or following message may be displayed (S53, S54). If the list is dragged in a second direction a message related to the selected message may be displayed (S53, S55).

FIGS. 6 and 7 illustrate diagrams of a display screen for controlling a mobile terminal according to a first embodiment of the present invention.

As illustrated in FIG. 6-1, a list of received or transmitted messages may be displayed on the touchscreen 400 (S51). Specifically, the messages may be sorted in top-to-bottom direction in relation to a reception or transmission time.

A corresponding message or information, such as a name or phone number, of a recipient or sender may be indicated for each item on the list. As illustrated in FIG. 6, the sender of the corresponding message may be displayed as letter from the alphabet. Additionally, a numeral may be added adjacent to the letter in order to distinguish a plurality of messages from a single sender.

A user may touch and drag the list of messages on the touchscreen 400 in a first direction, such as bottom-to-top (S52, S53), as shown in FIG. 6-1.

In one example, as the messages are scrolled from bottom to top a size of the scrolled messages may be set proportional to a length of the touch and drag.

As illustrated in FIG. 6-2, a message B-2 may be touched and dragged in a second direction, such as right-to-left. The second direction is different from the first direction (S52, S53).

As illustrated in FIGS. 6-3 and 6-4, as the selected message B-2 slides from right to left, another message B-3 may appear (S55). In this example, the message B-3 is related to the selected message B-2. For example, the message B-3, may be a message which had been sent by the sender B after the message B-2 was sent.

The related messages B-2, B-3, may construct a list which is different from the former list.

Additionally, message B-2 may be touched and then dragged in a direction opposite to the second direction, such as left-to-right. This is explained with reference to FIG. 7 as follows.

As illustrated in FIG. 7-1, message B-2 is touched and then dragged left to right. Furthermore, as illustrated in FIGS. 7-1 and 7-2 as message B-2 slides left to right, another message B-1 appears (S55). In this example, the message B-1 is a message which may have been sent by the sender B after the selected message B-2 was sent.

In the description above description if a message is touched and dragged in a direction, another message related to the selected message is displayed by replacing the selected message. Still, before the message is touched and dragged in a direction, a terminal may display a message related to the selected message before the touch and drag is performed.

FIGS. 8A to 8C illustrate diagrams of a display screen for controlling a mobile terminal according to a second embodiment of the present invention. For clarity and convenience of the following description a single message in a message list is exemplarily displayed in FIGS. 8A to 8C.

As illustrated in FIG. 8A-1, a specific message B-2 may be displayed on the touchscreen. Additionally, information on messages 405 related to the selected message may be displayed adjacent to the selected message B-2.

As illustrated in FIG. 8A, the information 405 indicates that there are seven messages related to the selected message B-2, including the selected message B-2. Additionally, the information 405 also indicates that the selected message B-2 is the second message of the seven messages.

In one example, the message B-2 illustrated in FIG. 8A-1 may be touched and dragged right to left. Another message B-3 related to the selected message B-2 may be displayed instead of the selected message B-2 after the touch and drag.
